Presbyopia is a symptom in which the elasticity of the lens is weakened and the image is not formed. However, as the use of smart phones increases, the age at which presbyopia symptoms appear is gradually decreasing. The closer the distance is from the smartphone, the less the focus of the eyes will be which making the letters and pictures on the smartphone screen appear blurred. In this study, we conducted a study on the interactions that helped to improve health of eye for people with presbyopia or those who have a habit that can facilitating presbyopia. As the distance of the smartphone from the eye is increased, the font size is increased to upgrading readability and the prototype is tested by 20 experimenters.

An actuated shape-changing interface with fast response and small pixel size using a liquid material can provide real time tangible interaction with the digital world in physical space. To this end, we demonstrate an interface that displays user-defined patterns dynamically using liquid metal droplets as programmable micro robots on a flat surface. We built a prototype using an array of embedded electrodes and a switching circuit to control the jump of the droplets from electrode to electrode. The actuation and dynamics of the droplets under the finger provides mild tactile feedback to the user. Our demo is the first to show a planar visio-tactile display using liquid metal, and is a first step to make shape-changing physical ephemeral widgets on a tabletop interface.

This demo presents the newly developed Human Body Communication (HBC) technology utilizing the NFC contactless communication and electric field coupling. The main advantage of this novel technology is its ability to provide more human-centric operation as compared to a conventional NEC communication. In our demonstrations, two applications are introduced. The first one is the illustration of user authentication being realized by shaking hands with a doll. The electric field type NEC by electric induction coupling is utilized. The second application demonstrates an Apple Pay on FIBC and two scenarios of "contact" communication with a finger to NEC reader and NEC transaction with a touch panel display are introduced. On outline of the structure of the demo system is also presented to explain the operational principle of the HBC.

The main goal of our research is to develop a haptic display that conveys the shapes, hardness, and textures of objects displayed on near-future 3D haptic TVs. We present a novel handheld device, GraspForm. This device renders the surface shapes and hardness of a virtual object that is represented in an absolute position in real space. GraspForm has a 2x2 matrix of actuated hemispheres for one fingertip, two actuated pads for the palm, and a force feedback actuator for the thumb. Our first experimental results showed that eight participants succeeded in recognizing the side geometries of a cylinder and a square prism regardless of the availability of visual information.

shapeShift is a compact, high-resolution (7mm pitch), mobile tabletop shape display. We explore potential interaction techniques in both passive and active mobile scenarios. In the passive case, the user is able to freely move and spin the display as it renders elements. We introduce use cases for rendering lateral I/O elements, exploring volumetric datasets, and grasping and manipulating objects. On an active omnidirectional-robot platform, shapeShift can display moving objects and provide both vertical and lateral kinesthetic feedback. We use the active platform as an encounter-type haptic device combined with a head-mounted display to dynamically simulate the presence of virtual content.

Multiplanes is a virtual reality (VR) drawing system that provides users with the flexibility of freehand drawing and the ability to draw perfect shapes. Through the combination of both beautified and 2D drawing. Multiplanes addresses challenges in creating 3D VR drawings. To achieve this, the system beautifies user's strokes based on the most probable, intended shapes while the user is drawing them. It also automatically generates snapping planes and beautification trigger points based on previous and current strokes and the current controller pose. Based on geometrical relationships to previous strokes, beautification trigger points act as guides inside the virtual environment. users can hit these points to (explicitly) trigger a stroke beautification. In contrast to other systems, when using Multiplanes, users do not need to manually set or do any kind of special gesture to activate, such guides allowing the user to focus on the creative process.

In this paper we describe a demo setup showing the potential usefulness of a novel single-handed manipulation technique, designed to be used with immersive Virtual Environments. The technique allows manipulation control over objects in the scene through the use of a single 3D widget, allowing easy and separated control of translation, rotation and scaling actions. The goal is to provide an intuitive, easy-to-use and accurate way to perform simple manipulation tasks using only one hand. user tests demonstrated that the widget is intuitive and effective.

In this paper, we propose a novel technology called "CheekInput" with a head-mounted display (HMD) that senses touch gestures by detecting skin deformation. We attached multiple photo-reflective sensors onto the bottom front frame of the HMD. Since these sensors measure the distance between the frame and cheeks, our system is able to detect the deformation of a cheek when the skin surface is touched by fingers. Our system uses a Support Vector Machine to determine the gestures: pushing face up and down, left and right. We combined these 4 directional gestures for each cheek to extend 16 possible gestures. To evaluate the accuracy of the gesture detection, we conducted a user study. The results revealed that CheekInput achieved 80.45 % recognition accuracy when gestures were made by touching both cheeks with both hands, and 74.58 % when by touching both cheeks with one hand.

Testing userinterfaces (UIs) is a challenging task. Ideally, every sequence of UI elements should be tested to guarantee that the application works correctly. This is, however, unfeasible due to the number of UI elements in an application. A better approach is to limit the evaluation to UI elements that affect a specific functionality. In this paper I present a novel technique to identify the relation between UI elements using the statically extracted data flows. I also present a method to refine these relations using dynamic analysis, in order to ensure that relations extracted from unreachable data flows are removed. Using these relations it is possible to more efficiently test a functionality. Finally, I present an approach to evaluate how these UI-aware data flows can be used as an heuristic to measure test coverage.

We present HapticDrone, a concept to generate controllable and comparable force feedback for direct haptic interaction with a drone. As a proof-of-concept study this paper focuses on creating haptic feedback only in 1D direction. To this end, an encountered-type, safe and un-tethered haptic display is implemented. An overview of the system and details on how to control the force output of drones is provided. Our current prototype generates forces up to 1.53 N upwards and 2.97 N downwards. This concept serves as a first step towards introducing drones as mainstream haptic devices.
